Final answer:
In the production cost report, the total costs accounted for equals the costs of the units started into production. The physical units accounted for equals the units that have been started into production.
Step-by-step explanation:
In the production cost report, the total costs accounted for equals the costs of the units started into production. This means that the total costs accounted for in the report represent the costs of the units that have been started into production.
On the other hand, the physical units accounted for in the production cost report equals the units that have been started into production. This also means that the physical units accounted for represent the number of units that have been started into production.
Therefore, the correct answer to the question is: c) Physical units accounted for equals the units to be accounted for.
